Taking to Instagram, the basketball player shared a snap of himself on the court.

Dressed in his Cleveland Cavaliers uniform and holding a ball, he completely ignored the numerous allegations - and the birth of his daughter True.

And a lot of his followers were less than forgiving.

He wrote: "WHAT AN ATMOSPHERE IN THE Q!! GREAT WIN #OnToTheNextOne"

People immediately jumped on the post to give Tristan a hard time about cheating on Khloe and about his choice of hashtag.

One asked him: "so how abt atmosphere at home?"

Another commented: "Everyone still hates you!!!!"

"Kim Kardashian unfollowed you," one told him.

While another asked: "Where’s the dislike button??"

And one exclaimed: "KHLOE DESERVES BETTER!!!!"

"Lush hashtag! Is that your motto when it comes to women too," another said.

Before this picture, Tristan hadn't posted anything on Instagram since April 5. True was born on April 12.

Just the day before baby True was born, a string of videos and pictures emerged online that allegedly showed Tristan kissing other women and rubbing his face in another's breasts.

Pictures also appeared to show him going back to a hotel with a mystery woman.

Someone later came forward, claiming to be the girl in those pictures, while declaring that she and Tristan were in love.

She shared a clip from a sex tape she claimed showed her and Tristan in the act and announced she was pregnant.

She then suddenly disappeared from social media, possibly because her account was blocked for sharing explicit material.

Last week, a clip of Khloe's sister Kim talking on The Ellen DeGeneres Show confirmed that Tristan had cheated.

"So, Khloe," Ellen says. "Poor Khloe".

"Poor Khloe," Kim repeats.

And Ellen continues: "I think everybody was heartbroken for her. I mean, literally days before she gives birth, her boyfriend is seen on video cheating and so, you, you have opinions about that?"

Kim says: "Like I don't even know how to describe it beside it's just so f****d up."

She added: "We really were rooting for Khloe and she's just so strong, and she's doing the best she can and it's a really sad situation all over.

"I kind of made this rule with my brother, like if there's a baby involved, I'm not gonna talk, I'm gonna keep it cute and keep it classy and not talk too bad, and I'm going to try not to say anything so negative because one day True's going to see this and you know, it's just so messed up."
